What is 3D and why your car GPS need 3D view?

3D becomes popular nowadays, it is everywhere in our daily life, no matter in a movie like Avatar, or 3D games, PSP, or hot 3D Samsung TV in the CES. Not even say in the commonly used car GPS. So what is 3D and why your car GPS need the newest 3D view map feature? Now I would like to introduce to you about this new tech, and give you kind advice to follow.

3D computer graphics (in contrast to 2D computer graphics) are graphics that use a three-dimensional representation of geometric data (often Cartesian) that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing.

You can see how Avatar movie is so hot around the world, since it is totally 3D made film. 3D is a motion picture that enhances the illusion of depth perception. Derived from stereoscopic photography, a special motion picture camera is used to record the images as seen from two perspectives (or computer-generated imagery generates the two perspectives), and special projection hardware and/or eyewear are used to provide the illusion of depth when viewing the film.

The Global Positioning System (GPS) is a navigation technology that provides precise time and location data by using 24 Navigation Satellite Timing and Ranging (Navstar) satellites. Each satellite completes one orbit of the Earth every 12 hours. They are positioned at an altitude that allows them to cover the same ground once every 24 hours (minus four minutes).
